Abstract

Abstract PURPOSE:To shorten the processing time of a control means by periodically reading operation data set in a setting switch circuit while updating them, in a period other than initializing operation, and thus modifying the operation data without interrupting the operation of a key telephone set. CONSTITUTION:Key telephone sets 1 and 2 are connected to the terminal interfaces 3 and 4 of a key telephone device 30, trunk lines 11 and 12 are connected to the trunk line interfaces 6 and 7 of the device 30, and a cross point 5 is connected between both the interfaces 3 and 4, and 6 and 7. Further, a control means 8 is provided for those interfaces 3 and 4, and 6 and 7, and the cross point 5, and this control means 8 is provided with a control circuit 20 and a memory 21. For this control means 8, a setting switch circuit 9 for varying and setting the operation data of the device 30 and a timer circuit 10 for counting a prescribed time are provided, and the operation data set in the circuit 9 are read in the circuit 20 periodically and repeatedly.
